The third-order process of spontaneous four-wave mixing (SFWM) has seen increasing use due to the CMOS-incompatibility and difficulty of integrating second-order material platforms, as well as due to the presence of third-order nonlinearities in common platforms. In integrated optics, SFWM's low efficiency is often compensated using on-chip nonlinear microcavities [1], however, excitation schemes...
The recently-introduced use of integrated frequency combs (on-chip light sources with a broad spectrum of evenly-spaced frequency modes, generated by four-wave mixing in optically-excited nonlinear microcavities) below optical parametric oscillation threshold for quantum state generation has provided a solution for scalable and multi-mode quantum sources [1, 2]. Pulsed quantum frequency combs, in...
The generation of optical quantum states on an integrated platform will enable low cost and accessible advances for quantum technologies such as secure communications and quantum computation. We demonstrate that integrated quantum frequency combs (based on high-Q microring resonators made from a CMOS-compatible, high refractive-index glass platform) can enable, among others, the generation of heralded...
A potential solution for the demand for highly stable pulsed lasers at hundreds of GHz repetition rates is represented by passively mode locked fiber lasers. These lasers are composed of a band-limited amplifier, a dispersive element and a nonlinear element. When a high finesse resonant filter is added intracavity, they emit pulses with a repetition rate equal to the filter free spectral range (FSR)...
